  • End parts 31 placed at the two extremities of the plate and mounted in a joint in the sliding eyelets have the double fimction of assuring tiie sliding of the main stracture onto said S-shaped supports and to fix tiie latter to said supports, besides being a cover and protection of the mechanism.
  • the central element 37 that is a filling stracture per increasing the mounting surface of the bindings on the plate, is linked to the main stracture by means of two screws.

Abstract

L'invention concerne un dispositif en plaque servant à optimiser la flexion et la réactivité et présentant des fonctions antivibratoires, destiné au ski. Le dispositif en plaque selon l'invention est placé entre les fixations et la surface du ski, permettant ainsi la flexion longitudinale libre, améliorant la réactivité dynamique du ski et réduisant sa vibration. Il consiste en quatre structures : deux structures contenantes (1) raccordées au ski et deux structures glissantes (2) auxquelles sont fixées les fixations et qui, par l'intermédiaire d'oeillets (34), permettent au ski de ne pas être pas influencé dans son flambage par le raidissage de la chaussure et de la fixation.
